The window comprises a frame structure and relative to the frame structure an openable, top-hung sash structure with an insulating pane (4) enchased between top, bottom and side members (5-7) of metal or plastic profiles. The insulating pane (4) is manufactured with dimensions corresponding to the exterior dimensions of the frame structure for direct abutment on a gasket (11-13) fastened to the exterior edge surfaces (17-19) of the top, bottom and side members of the frame structure, and the top, bottom and side members of the frame structure are made from a thermally well insulating material and on the interior side facing the light admitting area of the window covered by metal sheet profiles (31) for providing a good heat transmission to border areas of the insulating pane (4). The frame structure may consist of wood profiles (23) connected in profiled mitre joints (24).
